Currently info.magnolia.module.advancedcache.util.URLConnectionBuilder cannot be configured for any of the more secure protocol options.

This creates an issue for customers that wish to use Dynamic Page Caching and adhere to the security standards mandated by the company. DPC relies on URLConnectionBuilder inside info.magnolia.sitemesh.content.InjectUrlTag. If the sever is configured to only accept secure connections then the requests made for the dynamic pieces are blocked.
